Now that's a hybrid I can get behind.
I wonder how much it weighs or if it has a gyroscopic effect for the handling. Also, that can't be good in a crash to have several hundred pounds of metal spinning at 40,000rpm sitting next to you. |

Wow, scared me for a second - KERS is awesome! That ain't no Prius!

You have a link on the extra weight?

A porsche that winds itself like a watch...interesting but unnecessary

If cost is not a huge concern (and it wouldn't be for a one-off research project), there are plenty of ways to make a high rpm flywheel safe. You can use copious amounts of Kevlar to contain any debris, or you can use steel or composite wire wound around a small solid core instead of a solid metal disc.

Pretty pictures and all, but not very elegantly designed. Granted I'm sure it helps with weight distribution plopping it in the passenger seat, but still, seems cludgey [sic?].

I imagine the relative weight of the disk to the car will eliminate most gyroscope concerns. Also on that axis it won't affect handling going left/right.
I'm curious about the bearings they're using to spin the disk to 40k rpm. I've heard ppl talking about doing this in F1 cars for awhile now; just enough to give it a quick boost in the low end after hard braking. Here, they are describing it as a boost button or something. One more thing for the driver to worry about. I'd like to see some data on the weight of that thing, but 160kW is very impressive for such a small package. It can be charged much faster than batteries - almost like ultra capacitors. Glad to see hybrids are making their way to motorsports. |

I'm willing to bet that the system uses a pair of counter-rotating flywheels, which negates the gyroscopic effects, since the angular momenta cancel each other out. The flywheel based KERS systems people were proposing for F1 a few years back were the same way.

So in mullet terms we're talking about a 160 shot for your porsche?

That's cool. It's like the "turbo" button in video games.

so is there a 'turbo power' button?
I like to see the performance applications of the hybrid technology. Nick |

640hp electro-nitrous AWD Porsche ain't bad in my book.

I'll wait for Top Gear's impressions on this one.

I assure you that several hundred pounds are not spinning at 40000 rpm. Probably less than 20. You do know your turbo in your subie is about 1.5 feet from your right leg, and it spins over 70000 rpm.

looking at the tech pic, I thought that was a chaparral style street sucker.
